The Cybex Sirona S 360 is the ONLY convertible car seat to feature a 360-rotatable seat with load leg stability, linear side impact protection, and SensorSafe technology.

This Sirona S 360 rotating convertible car seat is the first model to include an innovative 360° rotatable seat with load leg technology, making switching between rear-facing and forward-facing positions quick and easy.

The Sirona S car seat's load leg stabilizes the seat and can significantly reduce crash forces. These features, combined with an EasyLock bar for quick, simple, and secure installation, offer advanced safety protection for children — and greater peace of mind for parents.

SensorSafe™

The smart-tech harness chest clip with SensorSafe™ technology makes the Sirona S SensorSafe convertible seat even safer, providing alerts when unsafe situations arise — including if a child unbuckles themselves while the vehicle is in motion, if the back seat has become too warm or too cold, if a child has been seated for too long, or if the driver accidentally leaves the child behind after the vehicle has been switched off. These alerts are provided through an installed vehicle receiver and the user-friendly smartphone SensorSafe App.

Product Features :

  • An innovative, one-hand 360° rotatable seat allows parents to easily get their child in and out — a signature feature of the Cybex Sirona S 360
  • The load leg stabilizes the car seat and can reduce rotation in certain crashes by up to 30%
  • The only convertible car seat in North America with a one-time vehicle belt installation for both rear-facing and forward-facing modes
  • EasyLock bar reduces the force needed up to 4x for quick, simple, and secure installation
  • A smart-tech harness chest clip with SensorSafe technology alerts parents if their child becomes unbuckled, the car temp gets too warm, or unsafe conditions arise
  • 12-position recline adjustment, even while the seat is in use
  • Linear Side-impact Protection absorbs up to 25% more impact in a collision, making the Cybex Sirona S 360 one of the safest convertible car seats
  • An anti-rebound design reduces car seat rebound movement
  • Magnetic buckle holders make entry and exit from the seat a breeze
  • A dishwasher-safe cup holder can be positioned on either side of the seat
  • 12-position, height-adjustable headrest with no-rethread harness

    Comfortable Ergonomic Chair for Long Workdays
    Color: Black, Color: Black
    I’ve been using this chair for my home office, and it’s been a great addition to my workspace. The seat cushion is thick and comfortable, even after several hours of sitting, and the mesh back keeps good airflow throughout the day. I especially like the adjustable headrest, which provides extra neck support when leaning back during breaks. Assembly was straightforward, the chair feels sturdy, and the wheels roll smoothly on my floor. The all-black design also gives it a professional look that fits well in any office setup. Overall, it’s a comfortable and affordable ergonomic chair that offers excellent value for the price.

    Sturdy but uncomfortable
    Color: Black
    The seat itself is sturdy and easy to put together, I’ve now had the product for 8 months and had no issues wear/tear despite nearly daily use, but… it’s not comfy, at all. The seat cushion has a texture to it that scrapes at my legs if I don’t have an extra pillow on it or am wearing shorts. Additionally, the seat pillow is just kind of hard. It doesn’t give very much at all, so if I sit on it for more than an hour or two at a time my butt starts to get really sore. It works as a budget option, but invest in a good seat pillow if you plan to sit in it for any length of time.

    A chair that does the job
    Color: Black, Color: Black
    I’m really happy with this chair overall. I wanted something comfortable, sturdy, breathable, and spacious enough for long hours at my desk when I work from home, and this chair delivered. I’d easily give this chair five stars because it exceeded my expectations in comfort, quality, and overall value. Comfort and Support The mesh back keeps it cool and comfortable during extended use. One of my favorite features is the adjustable lumbar support. You can manually position it exactly where your lower back needs support, and it fits the curve of my back perfectly. It provides great support without feeling too firm or uncomfortable. Build Quality and Design The chair itself feels solid and well-built. It doesn’t creak or make noise when shifting around, which makes it feel stable and high-quality. The seat is roomy and comfortable, and the overall design looks clean and modern. Easy Assembly It also came with an instruction manual that was extremely simple to follow, and assembly was very easy. I was able to put the chair together by myself in about 20 minutes without any help. Armrest Functionality I also like the armrests. They aren’t adjustable by height, but they do flip all the way up, which is surprisingly convenient. You can easily slide the chair under a desk or use it as an armless chair when needed. Packaging and Presentation Another thing worth mentioning is the packaging. Everything arrived extremely well-packed. Every individual part of the chair was wrapped securely, including bubble wrap protection for the components. The hardware and accessories were neatly organized, and the chair even came with the necessary tools for assembly in case you don’t own a drill or tool set. The presentation and packaging were excellent and showed real attention to detail. Overall Impression Overall, this is a fantastic office chair for the price: comfortable, supportive, sturdy, easy to assemble, and packaged exceptionally well. I’d absolutely recommend it and would confidently give it a five-star rating.

    Nice chair
    Easy to assemble and looks clean in my home office. The lumbar support is actually helpful, and I like that the arms flip up so I can tuck it under my desk. It’s comfortable for a full workday, though the seat could be a bit softer. Overall, solid value for the price.
